HER307GA-G

The HER307GA-G is a single-phase, full-wave bridge rectifier which is used to accurately rectify and regulate voltage levels in a variety of different medium- to heavy-duty consumer, commercial, and industrial applications. It is manufactured by International Rectifier and is available in a range of different power ratings, allowing it to be used in a wide range of applications, from a simple power adapter to solar inverters and servers.

The HER307GA-G is a fast-acting, highly efficient bridge rectifier which offers many advantages over traditional types of rectifiers. Firstly, it features a unique inherent power thermistor configuration, which provides a thermal protection mechanism whereby the device will turn off in the event of an overcurrent condition. This helps to reduce the risk of power supply failure due to thermal runaway. Secondly, it is designed with low forward voltage drop, allowing for greater efficiency in light and heavy-duty applications. Finally, its capability for higher frequency and greater reverse transient immunity makes it ideal for more demanding, high-power applications.

The principle of operation of the HER307GA-G is a relatively simple one. The device is fabricated on a single substrate, and consists of four diodes configured in a bridge circuit, as shown below. The two opposite corners contain the anode and cathode of the two diodes, which are connected to the AC power source. The third and fourth corners contain the anode and cathode of the two other diodes, which are connected to the load. When an AC voltage is applied across the bridge circuit, the diodes block the voltage in one direction, enabling the current to only flow in the other direction, thereby rectifying the AC signal. This rectified output is then applied to the load, providing a source of regulated DC voltage.

In summary, the HER307GA-G is a single-phase, full-wave bridge rectifier which is used in a variety of different applications. It features a unique power thermistor configuration, a low forward voltage drop, and is suitable for high-power, higher frequency applications. Its principle of operation is based on the bridge rectifier configuration, wherein four diodes are arranged in a bridge circuit to enable the rectification of an AC signal. It is an excellent choice for power supply design requiring fast rectification and regulation of voltage levels.
